Resolved Missing HD Space in iMac Fusion Drive

[Skadi]

Hello,

I am missing 250GB on my 1TB Fusion drive. I have completely formatted my drive in recovery but it still shows up as 750GB. This happened after something went wrong with my Bootcamp partition, I am not entirely sure what happened but it's gone. (And it used to be 250GB)

I don't know what to do to get this space back. Please help me, thanks!

[doublepost=1512641226][/doublepost]I have followed the steps from Weaselboy's post, and I am still missing 250GB. I now have 1 drive called Fusion of 120GB and 1 drive called Untitled of 634,25GB

UPDATE: I managed to make the Untitled drive into 999,86GB. Now I have 999,86GB on Untitled and 120GB on Fusion. How can I make these drives into 1 again? Preferably 1 of 1TB.

Thanks for your reply! I did follow these steps, and this is how it turned out.

Hmm... you must have missed something. Do "diskutil cs delete Fusion" to kill that and try again. Make sure you have formatted the individual drives first.

When I give that command I get 'Fusion does not appear to be a valid Core Storage Logical Volume Group UUID or name'

 

[Weaselboy]

Try again with the Logical Volume Group name up there that starts with BAC... paste in the whole string.

I think I got it to work! Does this look fine?

 

[Weaselboy]

Yup... there you go!
